jumper Posted July 28, 2010 Share Posted July 28, 2010 i have recently replaced the driver in my ashdown mag 115 (which had blown) with a celestion neo orange label 400 watt 8ohm and it sounds great. However now my mag 210 is being shown up to such an extent that i think an upgrade is in order to balance things out a bit. I see that the overall impeadence of the cab is 8ohm dose that mean that each of the 10's is 4ohms in series or 16 in parallel, (i think that thats the right way around) and if that is the case what about the tweeter? Dose this need upgrading or just leave it as it is? any thoughts or advice welcome. Quote Link to comment Share on other sites More sharing options...

fatgoogle Posted July 28, 2010 Share Posted July 28, 2010 Yep you want 16ohms. It means if both drivers are 150 watts youll get a 300 watt cab while 4 ohms wired to 8 means youll only have a 150 watt cab. I think this is right anyway.

jumper Posted July 28, 2010 Author Share Posted July 28, 2010 good point i hadn't thought of the posibility of one failing bringing the other down. i suppose the only way to find out what the cab was originaly is to check out the wiring within the unit!

As to 4 ohm drivers series versus 16 ohm drivers parallel, there will be very little difference electrically. There can be a major difference mechanically, due to different voice coil lengths. You want to use the option that has the higher xmax and xlim specs. Quote Link to comment Share on other sites More sharing options...
